Public Overridable Property Handle As IntPtr

Property Value

IntPtr

An IntPtr representing the native operating system handle. The default is the value of the InvalidHandle field.

Attributes: ObsoleteAttribute SecurityCriticalAttribute

Remarks

Assigning a new value to the Handle property does not close the previous handle. This can result in a leaked handle.

Do not use this property in the .NET Framework version 2.0 or later; use the SafeWaitHandle property instead. Setting this property to a valid handle also sets the SafeWaitHandle property, but setting it to InvalidHandle can result in a leaked handle.

Security

SecurityCriticalAttribute
Requires full trust for the immediate caller to set the property value. This member cannot be set by partially trusted or transparent code.

InheritanceDemand
Derived types must have UnmanagedCode to set the property value.
